S = 3/5 or 0.6
explanation
-4/0.8 = 2/s-1
divide the numbers on the left: -5 = 2/s-1
multiply both side by s-1: -5(s-1)=2
simplify: -5s + 5 =2
gather like terms: -5s= 2 - 5
simplify: -5s= -3
divide both sides by -5: x=3/5
Using Pythagorean theorem c^2=a^2 + b^2, we can find the missing side b.
Put values in equation.
18^2 = 8^2 + b^2
324=64+b^2
Subtract 64 from both sides
260= b^2
Take square root.
2√65=b
or
b=16.12
Answer: b=2√65 Radical form. or b=16.12 Decimal form.

Pi is irrational so multiplying it by a fraction will result in an irrational number.
square root of non perfect square will also give an irrational.
adding pii to rational will give irrational.
The answer is the las t One:- Multiplying a fraction by a repeated decimal - because a repeated decimal can be written as a fraction.
